- To study the effect of quasi-DC discharge plasma on the cold flow field, under the low equivalent ratio of ethylene and air in the combustor of scramjet, a quasi-DC discharge plasma model crossed the front wall of the cavity has been settled. Under the different plasma actuation intensity, the effect of plasma on combustion chamber temperature, pressure distribution, cavity drag force characteristics and mass exchange rate of the cavity are numerically studied. The results showed that, the quasi-DC plasma improved the temperature in the cavity obviously. Due to the plasma "cutting" effect on the shear layer, the impact of the shear layer on the rear edge of the cavity has been weakened. With the increasing of the plasma actuation intensity, the drag force of the cavity decreases slightly, meanwhile, the mass exchange rate of the cavity increases remarkably.
